Essential Tremor vs Parkinson’s
To distinguish between the two diseases, a neurologist specializing in movement disorders will perform neurological testing and evaluate features of the tremor including frequency, amplitude, pattern, and distribution.
Parkinson's disease is much less common than essential tremor, and it presents itself in markedly different ways, however there are similarities. While treatments overlap in some areas, getting the best care requires the right diagnosis. The two conditions have key differences to look for:
Below are some of the differences & resemblances between the two diseases:
(1) Resting tremor occurs when the muscle is relaxed, such as when the hands are resting on the lap. With this disorder, a person’s hands, arms, or legs may shake even when they are at rest. Often, the tremor only affects the hand or fingers. This type of tremor is often seen in people with Parkinson’s disease and is called a “pillrolling” tremor because the circular finger and hand movements resemble rolling of small objects or pills in the hand.
Action tremor occurs with the voluntary movement of a muscle. Most types of tremor are considered action tremor. There are several sub-classifications of action tremor, many of which overlap.
